Product details
The BA3901 Pageant Power Combiner is a certified accessory which remotely combines the quad outputs of a BA243. For applications in IIC hydrogen atmospheres, this allows longer field wiring to be used between a BEKA Power Isolator and a BA3101 Operator Display.  The BA3901 Power Combiner has four pairs of input terminals and mounts on to the rear of any plug-in Pageant CPU module which distributes power within the BA3101 Operator Display.

The BEKA BA243 Power Isolator has four separate galvanically isolated intrinsically safe outputs. It has been specifically designed to power a Pageant BA3101 Operator Display fitted with a BA3901 Power Combiner located in a IIC hydrogen atmosphere.
