Input Section Specifications

Item Specification
Model CRT1B-ID02S CRT1B-ID02S-1
I/O capacity 2 inputs
Internal I/O common NPN PNP
ON voltage 10.5 VDC min. (between each input terminal
and the V terminal)		 10.5 VDC min. (between each input terminal
and the G terminal)
OFF voltage 5 VDC max. (between each input terminal and
the V terminal)		 5 VDC max. (between each input terminal and
the G terminal)
OFF current 1.0 mA max.
Input current 3.0 mA max./input (at 10.5 VDC)
Sensor power supply voltage Communications power supply voltage + 0 V (max.)
Communications power supply voltage - 1 V (min.)
ON delay 1.5 ms max.
OFF delay 1.5 ms max.
Number of circuits per common 2 inputs/common
Power short-circuit detection Supported
Isolation method No isolation
Input indicators LEDs (yellow)
Degree of protection IEC standard IP20
Installation Screw installation (M4)
Power supply type Network power supply
Communications power supply
current consumption * 		65 mA max. for 24-VDC power supply voltage
80 mA max. for 14-VDC power supply voltage		 45 mA max. for 24-VDC power supply voltage
65 mA max. for 14-VDC power supply voltage
Weight 70 g max.

* The current consumption is for Bit Slave Unit communications current when all inputs are OFF, i.e., it does not include
   input device current consumption. The communications power supply is also used for the I/O power supply for sensors.
   Be sure to consider the sensor current consumption and the number of sensors connected in addition to the
   communications power.
   The power supply current consumption is expressed by the following formula.
   Communications power supply current consumption = Bit Slave Unit communications current consumption + (Bit Slave
   Unit input current x number of inputs used) + (sensor current consumption x number of sensors used)

1.5 ms max.
OFF delay
Number of circuits per common 2 outputs/common
Load power short-circuit detection Supported
Isolation method No isolation
Output indicators LEDs (yellow)
Degree of protection IEC standard IP20
Installation Screw installation (M4)
Power supply type Network power supply
Communications power supply
current consumption * 		55 mA max. for 24-VDC power supply voltage
75 mA max. for 14-VDC power supply voltage		 55 mA max. for 24-VDC power supply voltage
70 mA max. for 14-VDC power supply voltage
Weight 59 g max.

* The current consumption is for Bit Slave Unit communications current when all outputs are OFF, i.e., it does not include
   output device load current consumption. The communications power supply is also used for the I/O power supply for
   actuators. Be sure to consider the actuator load current consumption and the number of actuators connected in addition
   to the communications power.
   The power supply current consumption is expressed by the following formula.
   Communications power supply current consumption = Bit Slave Unit communications current consumption + (Bit Slave
   Unit input current x number of inputs used) + (actuator load current x number of actuators used)
