Vdc (A1500LC) supply output.
Option 1
: 2 SPST alarm relays (ALM3 and ALM4).
Option 2 : 4-20 mA / 0-20 mA analog output.
Option 3 : RS485 Modbus communication interface.
Option 4 : 24 Vac/Vdc power supply input.

Sensor or input signal connection
 These connections should be well done and terminals must be well tightened.
 Thermocouples must be installed with proper extension or compensation cables.
 Pt100 RTDs must be 3-wire connected and the wires connected to terminals 17
and 18 should have the same electrical resistance (same wire gauge) for proper
cable distance compensation.
 Four-wire RTDs can be connected by disconnecting the fourth wire. Two-wire
RTDs can be connected by shortening terminals 22 and 23 and connecting the
Pt100 to terminals 16 and 17.
