zen-20c2dt-d-v2 Omron Corporation, zen-20c2dt-d-v2 Datasheet - Page 14

• Manufacturer Part Number: zen-20c2dt-d-v2
• Description: Programmable Relay
• Manufacturer: Omron Corporation

CPU Units with 20 I/O Points
For Connections to a Negative Common (PNP Connection)
For Connecting Analog Input Devices to Input Terminals Ia and Ib
For Connections to Positive (+) Common (NPN Connection)
Note: When connected to the positive (+) common, Ia and Ib cannot be used as analog inputs.
Expansion I/O Units
Note: 1. Supply power to both the CPU Unit and Expansion I/O Units from the same power supply and turn them ON and OFF at the same time.
For Connections to Negative (−) Common
For Connections to Positive (+) Common
Note: When connecting an analog input device, always connect the negative side to the COM terminal.

2. ZEN-8E1AR Expansion I/O Units with AC inputs cannot be connected to CPU Units with DC power supply.
3. The input circuit commons for ZEN-8E1DR Expansion I/O Units with relay outputs are each internally connected to one side of the power
4. ZEN-8E1DT Expansion I/O Units with transistor outputs do not need to be connected to a power supply.
