Analog Inputs (1-8)
(Optional)
4-20 mA, 2-wire or 3 -wire, internally powered by 24 VDC, 25 ohm input resistance,
1000 ohm maximum load. Typical response time <10 seconds
Outputs
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
Isolated, 500 ohm max. resistive load, internally powered
Agency Approvals
CSA C22.2 No. 61010-1:2012 3rd Ed.
Note: For EN61000-4-6, and EN 61000-4-3, the controller meets performance criteria B.
*Class A equipment: Equipment suitable for use in establishments other than domestic, and those directly connected
to a low voltage (100-240 VAC) power supply network which supplies buildings used for domestic purposes.
