Safety relay for 24 V safety circuits

The Banner UM-FA-1 is a universal safety relay module designed for 24 V ac/dc supply. It provides one dual or single-channel safety input compatible with light curtains, scanners, e-stops or interlocks. Two normally-open safe outputs and one normally-closed auxiliary output each switch up to 7 A. The 22.5 mm wide housing mounts on DIN rail with removable screw terminals.

Practical limits of the 24 V supply and I/O

The module operates from 24 V ac/dc with a ±10 % tolerance and consumes 2 W or 2 VA. Safety inputs accept 10-20 mA at 12 V dc for dry contacts or 5-20 mA at 18-28 V dc for PNP solid-state devices. Reset input draws 40-100 mA. Maximum ambient temperature is 50 °C at 90 % relative humidity. Typical response time is 25 ms with a 250 ms recovery time.

Build quality and daily installation

The red polycarbonate housing measures 84 x 22.5 x 118 mm and carries a 20 million-operation mechanical life rating. Removable screw terminal blocks allow wiring to be completed before the module is clipped in place, simplifying panel assembly and future replacement. Vibration resistance is rated at 10-55 Hz. Part number 81228 identifies the unit for ordering and documentation.

Questions about this item

Should I choose the 22.5 mm wide module or a different width for my DIN rail?

The UM-FA-1 is 22.5 mm wide and fits standard DIN rails. Its removable screw terminals simplify wiring in tight panels.

What does the 25 ms typical response time mean for my safety circuit?

The safety outputs switch off within 25 ms after an input opens, meeting typical safety-light-curtain and e-stop requirements.

How does the 24 V ac/dc supply affect compatibility with my control cabinet?

The module accepts 24 V ac or dc within ±10 %, so it works with both AC and DC control supplies without a separate converter.
