Mode Switch Label
Single Relay Interlock Mode (SPDT)
Mode Switch Setting 000
This mode provides the ability to control each of the four SPDT relays through switch inputs A through D.
When one relay is activated or turned on, the other relays are turned off. For example if the user turns on Relay
#1 using switch input “A”, then Relays 2, 3 and 4 are turned off. Switch input E turns off all Relays.
Multiple Relay Activation – Alternate Action
Mode Switch Setting 001
This mode toggles each individual Relay on or off. The first switch closure turns the relay on and the second
switch closure turns the relay off. Any combination of switches may be activated at the same time. Switch input
E, when activated, overrides all other switch inputs and turns off all relays.
Multiple Relay Activation – Momentary ON
Mode Switch Setting 010
This mode turns on the corresponding relay for the duration of the switch closure. Switch E turns on all relays
for the duration of the closure. Any number of relays can be operated at the same time.
Dual Relay Mode (DPDT) - Push On/Push Off
Mode Switch Setting 011
This mode provides the ability to pair up the Relays for use in a Dual Relay application. Each pair R1/R2 and
R3/R4 effectively become DPDT relays when configured in this mode. Switch A turns on relays 1 & 2; Switch
B turns off relays 1 & 2. Switch C turns on relays 3 & 4, and switch D turns off relays 3 & 4. Switch E turns
off all relays.
Dual Relay Modes (DPDT) - Alternate Action
Mode Switch Setting 100
This mode provides the ability to toggle each pair of Relays. Switch “A”, toggles relay pair R1/R2 and Switch
C toggles relay pair R3/R4. Switch D unconditionally turns on both pairs of relays and switch E
unconditionally turns off both pairs.
Dual Relay Modes (DPDT) Alternate Pulsed 0.25 sec
Mode Switch Setting 101
This mode provides the ability to pulse each relay for a given application that may require the use of a trigger
pulse for turning on some type equipment.
• Switch A the first press sends a ¼ second pulse to relay 1; the second press sends a ¼ second pulse to
relay 2.
