Note: In the graphics below notice that the Slot A connector does not show labeling for the outputs. Labeling for Slot A outputs is based on the controller part number.
Ó Warning: Use National Electric (NEC) or other country-specific standard wiring and safety practices when wiring and connecting this controller to a power source and to electrical sensors or peripheral devices. Failure to do so may result in damage to equipment and property, and/or injury or loss of life. Note: Maximum wire size termination and torque rating: • 0.0507 to 3.30 mm2 (30 to 12 AWG) singlewire termination or two 1.31 mm2 (16 AWG) • 0.8 Nm (7.0 lb.-in.
Note: In the drawings below for each input notice that the Slot A connector labeling is identified. Note: When using a 2 wire RTD, jumper S1 and T1 together Inputs All inputs shown below represent input 1 (the only input) and are to be connected to slot A of the Limit Control.
Outputs Please note all outputs are connected exclusively to slot A. Output availability is based on the part number of your Limit Control. Note: In the drawings below for each output notice that the Slot A connector labeling is identified with the corresponding part number below.
Outputs (cont.) Switched DC • 22 to 32VÎ(dc) @ 30mA maximum supply current • short circuit limited to <50 mA • 22 to 32VÎ(dc) open circuit voltage • Use dc- and dc+ to drive external solid-state relay. • DIN-a-mite compatibility is for output 1 only.
