T1F-08DA-1 - 8 Channel Analog Current Output
*Max. allowable output power dissipation. For example, at 60
°
C and 24VDC, there
must be a load of at least 250
Ω
on the output circuit. Smaller loads will damage the
analog output circuit.

NOTES:
1. Shields should be connected to the 0 V terminal of the module or the 0 V of
the power supply.
2. Unused current outputs should remain open (no connections) for minimum
power consumption.
