4 Relay / 10 Amp Module
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 20 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.

Relay / 3 Amp Module
The 4120-3003 and 4100-3203 Relay Modules — both of which consist of the 565-045 Daughter Card and the 562-727 Motherboard — include
eight relays. Each relay controls one set of contacts and a separate 5 A fuse protects each contact. Eight feedback circuits, which are typically used to
monitor the state of a separate set of contacts (such as the sail switch on a damper or the NO or NC 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 3 A at 30 VDC or 0.5 A at 120 VAC. Refer to Error! Reference source not found.
for the designations of the contacts and feedback circuits. All wiring connections are made to the 562-727 Motherboard.
