- Output 1 is dedicated to controlling the internal SSR.
- If 75A heat sink is selected below 1 Digital Input (6) will be factory set and fixed as
the SSR over temperature Digital Input.

Integrated Limit Controller
1 universal input and 2 outputs
A
None
L
Limit control module (output 3, 5A, Form C mech. relay; output 4, 2A, Form A mech. relay)
B

Mechanical Contactor and Power Sup-
ply
If the limit controller was ordered, the contactor will come
internally connected to output 4 on the limit module. The
contactor has external contacts available for daisy chaining to
other branch circuit components.
AH
No contactor and universal high voltage power supply 100 to 240V‡ (ac/dc)
AL
No contactor and universal low voltage power supply 24 to 28V‡ (ac/dc)
B1
Single pole, 40 A Watlow contactor, 24VÅ (ac) power supply
B2
Single pole, 40 A Watlow contactor, 110 / 120VÅ (ac) power supply
B3
Single pole, 40 A Watlow contactor, 208 / 240VÅ (ac) power supply
F1
Dual pole, 40 A Watlow contactor, 24VÅ (ac) power supply
F2
Dual pole, 40 A Watlow contactor, 110 / 120VÅ (ac) power supply
F3
Dual pole, 40 A Watlow contactor, 208 / 240VÅ (ac) power supply
Communications
A
Standard software to connect to pc software, remote user interface (RUI) and other EZ-ZONE devices
M
Modbus™ RTU communication port to connect to non-ST products

Heat Sinks
A = None (no DIN-rail mount) D = 75A, 24VÎ (dc) fan cooled
B = 25A E = 75A, 115VÅ (ac) fan cooled
C = 40A F = 75A, 240VÅ (ac) fan cooled
Note: If heat sink option D, E or F is selected the integrated PID controller options B, E, D or C must also be ordered.
The 75A heat sink includes an SSR over-temperature thermostat shut-down feature factory connected to Digital Input 6.
