14.1 FEATURES OVERVIEW
The Dual Relay Output Board and 4 Relay Output Board provides two
isolated (354 V per IEC spacing, 500 test), 7-ampere Form-C
electro-mechanical relays that enable setpoint-triggered switching to an
external device (plus two 1-ampere Form-C electro-mechanical relays for 4
Relay Option). Each relay can accommodate a single setpoint. 200 W,
2500pf snubbers are provided for each normally open contact.
These options may not be used with parallel BCD Board Option. Figure 14-1
and 14-2 shows the board connections and jumper locations.
