As part of your installation, you might need to include a Mercury MR16in interface module.
The following diagram demonstrates how to connect the module.
|A||Inputs||16 general-purpose, programmable-circuit type.|
|B||Address switches||Used to set the device address. For more information on address settings on the Mercury module, refer to the manufacturer's instructions.|
|C||Line termination||For modules at end of line, install jumper for 120 Ohm line termination (J2 is not used).|
|D||RS-485||RS-485 bus connection to other Mercury modules.|
MR16in: 5A inductive, 0.6 PF
MR16in-S3: NO: 5A, NC: 3A, inductive, 0.6 PF
|F||Power In||Connect + to VIN (observe polarity). Connect - to GND. Use 20 AWG wires minimum.|
