Mechanical relays:
At 115 VAC, 10 amp (resistive), 1/8 HP
At 230 VAC, 6 amp (resistive), 1/8 HP
R1, R2, R3, and R4 relays are fused together as one group, total current for this group must not exceed 5.5A
R5, R6, R7 and R8 relays are fused together as one group, total current for this group must not exceed 5.5A.
Relays 1-8 may be dry contact or may switch line (mains) voltage, depending upon model code; refer to Figure 4. Powered
relays have both NO and NC terminals available. Only powered relays are fused.
Digital:
USB
Ethernet, 10 Base T
OPTIONAL
4-20 mA (1-4):
Isolated, 500 ohm max. resistive load, internally powered
