General Electric IC200UDR228 and IC200UDR440 are VersaMax Micro PLC controllers with 24 Vdc inputs and relay-output field interfaces. IC200UDR228 is the 28-point 12/24 Vdc supply unit, while IC200UDR440 is the 40-point unit with 24 inputs and 16 relay outputs.
The two General Electric records use removable terminal strips and serial communication ports, but their point counts, DC supply arrangements and output allocations are different. The complete model must stay with the panel wiring and application program.

System Integration
VersaMax Micro PLC controllers
The General Electric IC200UDR228 / IC200UDR440 pair links discrete field circuits to a VersaMax Micro CPU and serial control path. This detail belongs to the selected configuration and should not be inferred from the base family alone.
01
UDR228 field map
IC200UDR228 / IC200UDR440: the 28-point UDR228 provides sixteen 24 Vdc inputs, one 24 Vdc output and eleven normally-open relay outputs. This detail belongs to the selected configuration and should not be inferred from the base family alone.
02
UDR440 field map
IC200UDR228 / IC200UDR440: the UDR440 provides the 40-point arrangement with 24 inputs and 16 relay outputs. This detail belongs to the selected configuration and should not be inferred from the base family alone.
03
Serial path
IC200UDR228 / IC200UDR440: port 1 supports SNP/SNPX slave; Port 2 supports SNP/SNPX master/slave, Modbus RTU master/slave and Serial I/O. This detail belongs to the selected configuration and should not be inferred from the base family alone.
04
Operating Characteristics
VersaMax Micro PLC
IC200UDR228 / IC200UDR440: the two controllers differ in power and output behavior that directly affects the control cabinet. This detail belongs to the selected configuration and should not be inferred from the base family alone.
Supply rangeRelay contactsHigh-speed channelExact model record
01
Supply range
IC200UDR228 / IC200UDR440: uDR228 accepts 9.2–30 Vdc; its Q1 DC output is rated 100 mA at 12/24 Vdc. This detail belongs to the selected configuration and should not be inferred from the base family alone.
02
Relay contacts
IC200UDR228 / IC200UDR440: uDR228 relay outputs are normally-open 2 A circuits; field loads require an external AC or DC source. This detail belongs to the selected configuration and should not be inferred from the base family alone.
03
High-speed channel
IC200UDR228 / IC200UDR440: uDR228 Q1 can be configured as a standard output, high-speed counter, pulse-train or PWM output. This detail belongs to the selected configuration and should not be inferred from the base family alone.

Frequently Asked Questions
Questions tied to the exact model
What is the main wiring difference between General Electric IC200UDR228 and IC200UDR440?
General Electric IC200UDR228 uses sixteen inputs, one DC Q1 output and eleven relays, while IC200UDR440 uses the 40-point arrangement with twenty-four inputs and sixteen relay outputs.
What supply must be available for General Electric IC200UDR228?
General Electric IC200UDR228 accepts 9.2–30 Vdc; its Q1 output is a 12/24 Vdc positive-logic output rated 100 mA.
Can the Q1 channel on General Electric IC200UDR228 be used for pulse output?
Yes. Q1 can be configured as a standard output, high-speed counter, pulse-train or PWM output; the relay channels cannot provide those pulse functions.
Why are the two serial ports on General Electric IC200UDR228 important?
Port 1 is the RS-232 SNP/SNPX slave path, while Port 2 is the RS-485 path for master/slave SNP/SNPX, Modbus RTU or Serial I/O.
What does the 40-point designation mean on General Electric IC200UDR440?
It identifies the controller class with twenty-four 24 Vdc inputs and sixteen relay outputs, not merely the number of program variables.
What must be retained when replacing General Electric IC200UDR228 or IC200UDR440?
Retain the exact model, terminal allocation and serial-port role so the replacement matches the existing program and field wiring.
