To reduce the susceptibility to noise, power analog modules and digital modules from separate power supplies. Do not exceed a length of 10m (33ft) for dc
power cabling.
Do not daisy chain power or ground from this module to any ac or dc digital module terminal base unit.
Also, total current draw through the terminal base unit is limited to 10A. Separate power connections to the terminal base unit may be necessary.
ATTENTION
Connections are for 1794-TB3G, -TB3GK and -TB3GS
(TB3G shown)

Connect cable shields to Chassis Gnd terminals.
All '24V Pwr' and 'RET' terminals
are sourced power provided for
the sensors. Do not connect external
power to these terminals.
These outputs provide power for up
to four 24Vdc devices at 15mA each--for
a total of 60mA. Channel 0 '24V Pwr'
and channel 1 '24V Pwr' are each current
limited to 30mA maximum.
NC = No connect
