Module IC200UDR164-DKC IC2OOUDR164-DKC IC200UDR164DKC

IC200UDR164-DKC | GE Fanuc VersaMax Micro PLC — 40 DI + 24 Form C Relay / 120–240VAC / 8 HSC / RS-232C / Up to 4 Expansion Units / Rev DKC

64-Point PLC, AC-Powered — One Housing, No Separate Power Supply

The IC200UDR164-DKC is a complete micro PLC — processor, power supply, and all 64 I/O points in one body. No external 24VDC supply is needed. Mains AC (100 to 240V) connects directly to the unit, which internally converts and distributes power to the PLC logic and all 40 input circuits.

The "164" in the part number carries the key specification: 120–240VAC input power. Its equivalent, the IC200UDR064, provides the same 40DI + 24 relay I/O but operates from a 24VDC supply. Both models are functionally identical in logic and I/O — the power supply voltage is the only selection criterion between them.

The DKC suffix identifies the hardware revision of this build. Revision variants (such as AD, CB, DKC) reflect component or manufacturing updates while maintaining programme and functional compatibility with other IC200UDR164 revisions.

Key Specifications

Form C Relays — Three Terminals, One Output Point

Each of the 24 relay outputs is Form C (SPDT): normally open (NO), normally closed (NC), and common (COM) terminals are all available at the terminal strip.

For machine builders, this contact form offers flexibility without extra hardware. One output can simultaneously close a "running" status lamp circuit (NO) and open a "stopped" interlocking circuit (NC). The COM terminal accepts any voltage within the relay's switching rating — 120VAC loads, 230VAC loads, and 24VDC loads connect to the same relay output bank without isolation hardware, because the relay contact is galvanically separate from the PLC's internal logic supply.

Application Scenarios

AC panel with mixed-voltage field devices: The unit connects to the AC supply bus directly. Relay outputs independently switch 230VAC motor contactors on one group and 24VDC solenoid valves on another — all from the same relay bank without voltage separation hardware.

Production batch counting: Multiple conveyor lines each feeding a pulse sensor to an HSC input. All 8 counters run simultaneously, accumulating product counts between programme scans without loss.

Distributed automation: The base IC200UDR164-DKC plus 4 expansion units reaching up to 128 I/O total — covering a complete machine without moving to a larger PLC architecture.

FAQ

Q1: How does the IC200UDR164-DKC handle positive and negative logic inputs?

All 40 input points support both positive and negative logic (PNP source and NPN sink) by wiring configuration — the same hardware point accepts either convention. PNP (positive logic) wires the field device to supply current into the input terminal; NPN (negative logic) wires it to pull current from the terminal to common. No parameter setting or hardware modification is required — the wiring determines the polarity.

Q2: What programming software and languages does the IC200UDR164-DKC support?

Proficy Machine Edition is the primary programming environment for the VersaMax Micro PLC. Connection to the IC200UDR164-DKC is via the RS-232C programming port using an IC200CBL001 cable or equivalent. Proficy Machine Edition supports Ladder Diagram (LD) and Instruction List (IL). Earlier Logicmaster software is also compatible with older firmware versions.

Q3: Can relay outputs switch both AC and DC loads from the same output bank?

Yes. Each Form C relay's common (COM) terminal accepts the field supply voltage independent of the PLC's internal logic. Different outputs in the same bank can switch different field voltages simultaneously — one relay at 120VAC, the adjacent one at 24VDC — because each relay's contact is isolated from all others. Ensure the specific load voltage and current are within the relay's rated switching capacity.

Q4: What types of VersaMax Micro expansion units are compatible?

VersaMax Micro expansion units covering digital inputs, digital outputs (relay and transistor types), analogue I/O, and combination digital/analogue configurations are compatible. Up to four expansion units of any mix connect to the base unit's expansion connector. The IC200CBL501 cable is typically used for expansion unit connection.

Q5: What is the hold-up time for the AC power supply on the IC200UDR164-DKC?

The AC power supply section provides a hold-up time of 10 milliseconds at 85 to 100VAC input voltage — the PLC continues operating for 10ms after a supply dropout at low-line AC voltage before the internal DC bus collapses. At normal supply voltage, hold-up time exceeds this minimum. This protects against brief AC line interruptions causing unnecessary programme stops, particularly relevant in facilities with unstable utility supply.
