51198831-100 Honeywell Controller module Brand new

A DC fused terminal block (TB) needs to be mounted inside the non-standard Honeywell cabinet to

terminate the incoming DC power cord from the external remote DC power supply. From this

terminal strip, a pair of wire with 18 AWG (0.82 mm2) terminates on the rail-mounted UIO TB. See

Refer : DC power line wiring through system tray in the section Wiring connections to view the

connections of fused TB and FOE.

The below specifications are applicable for each rail-mounted UIO module.

Limiting

Power supply

should be capable

of operating

without damage

continuously.

For power supply(ies) of 20A or less, the soft

limit is 135%.

For power supply(ies) between 20A to 40A, the

soft limit is 120%

For safety reasons, once the hard limit (200%)

is reached, the power supply must shutdown

the DC output (0 volts).

No component

rating should

be exceeded

during an

overcurrent

condition.

24V Power

down

When 24V rail falls below 19V, the output

voltage shall monotonically decrease until a

reapplication of the AC line input for proper

system shutdown/operation

STABILITY

UNDER

BROWNOUT

CONDITIONS

When the Input AC line voltage is below the

minimum operating limit (e.g., between 0 and

85 VAC) the power supply will not be damaged.

The difference between the power-up and

power- down thresholds shall be 10% of the

low line operating limits
