The 4120-3002 and 4100-3202 Relay Modules ⎯ both of which consist of the 562-952 Daughter
Card and the 562-951 Motherboard ⎯ include four relays, each rated at 10 A at 30 VDC or 10 A
at 120/240 VAC. Each relay controls two sets of contacts and a separate 15 A fuse protects each
set of contacts. Four feedback circuits, which are typically used to determine the state of a
separate set of contacts (such as a set of contacts on a motor), are also provided.
All contacts are Form C, dry contacts, meaning the Common terminal is connected to the
Normally Closed terminal when the relay’s coil is in the de-energized state. The maximum load
that can be wired to the contacts is 10 A. Refer to Figure 16 for the designations of the contacts
and feedback circuits. All wiring connections are made to the 562-952 Motherboard. The NO,
NC, and COM designations are silkscreened on the motherboard.
