Terminal-block Unit

Model	E39-TM1
*Power supply voltage 1**	12 to 24 VDC ±10%, ripple (p-p) 10% max.
Sensor power supply	11 to 23 VDC (power supply voltage -1 V)
Current consumption	40 mA max. + Sensor current consumption (total: 100 mA max.)
Response speed	1.2 ms max.
Number of inputs	1 point
Input signals	NPN/PNP no-voltage input (contact and non-contact), switchable
Input operating configuration	N.O./ N.C., switchable
Indicators	Input signal display (orange)
*Ambient temperature 2**	Operating: Groups of 1 to 3 Units: -25 to 55°C (with no icing or condensation) Groups of 4 to 8 Units: -25 to 45°C (with no icing or condensation) Groups of 9 to 16 Units: -25 to 40°C (with no icing or condensation) Storage: -30 to 70°C

*1. The power supply for the E39-TM1 is provided from the Communications Unit (order separately). Use an E3X-CN02
(order separately) Connector.
*2. When 4 or more Units are grouped together, the current consumption per Unit must not exceed 75 mA.
When using together with the E3X-DA-N Fiber Amplifiers, connect the E39-TM1 Units at the end of the group.
In this case, the upper limit for the ambient temperature for the E3X-DA-N Amplifiers is the rated upper limit -5°C.
