1. Introduction
The General Purpose Input/Output Modules are part of CTI Products’ MCN™
Monitoring and Control Network. Versions are available with combinations of
opto-isolated inputs, SSR (Solid-State Relay) outputs, or mechanical relay
outputs. They can be used to monitor and control a wide range of devices at
remote sites, including:
• Generators
• Doors / Intrusion alarms
• Door Locks
• Gate Controls
• Power Fail
• Temperature Alarms
• Microwave / T1 Link Status

Table 1 – Standard Models
Inputs are optically isolated, accept voltage inputs of 12 - 24 VAC/VDC
(nominal), and can be monitored with a PC running the MCNRCD Software.
Outputs are controlled from a PC running the MCNRCD Software, and can be
either latching or momentary.
