Warning
Turn the power supply to the instrument off before wiring or checking.
Working on or touching the terminal with the power switched on may result in severe injury
or death due to electrical shock.
• O1 (OUT1): Limit control output
• A1: A1 output
• A2: A2 output (EV2 option)
• EXT.RESET: External reset input
(EI option)
• RS-485: Serial communication
(C5 option)
(Fig. 4-1) • DC: Direct current,
DC voltage input
• TC: Thermocouple input
• RTD: Resistance temperature
detector input
Notice
• The terminal block of the BCS2 is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened by the terminal
screw.
• Use a thermocouple and compensating lead wire that correspond to the sensor input specification
of this controller.
• Use the 3-wire RTD which corresponds to the input specification of this controller.
• This controller does not have built-in power switch, circuit breaker and fuse. Therefore, it is
necessary to install a power switch, circuit breaker and fuse in the circuit near the external
controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)
• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).
• For the OUT1 (Limit control output terminals 7- 8), externally use a relay according to the capacity
of the load to protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires to
avoid external interference.
• Do not apply a commercial power source to the sensor connected to the input terminal nor allow
the power source to come into contact with the sensor.
Lead wire solderless terminal
Use a solderless terminal with an insulation sleeve in which an M3 screw fits as shown below.
