Simplex 4100-3204 Relay Module

The 4100-3204 Relay Module includes 4 relays, each rated at 2 A. Each relay controls two sets of contacts and a separate 3 A fuse protects each set of contacts. Four unsupervised feedback circuits, which are typically used to determine the state of a separate set of contacts (such as the sail switch on a damper), are also provided. For battery calculation purposes, the module draws 18 mA in the normal supervisory condition and 70 mA with the relays activated.
