OBM-4

£9.00

The OBM-4 output booster/buffer module converts eight of the outputs of an MTP-7 or MTP-8 to active high, pull-up type. This allows the MTP-7 or MTP-8 to be used to control existing instruments that have active high inputs and are impractical to swap over to active low. Taking the place of any usual ULN2803A octal output driver chip, an OBM-4 is quick and easy to install and requires no soldering. Each OBM-4 module controls 8 outputs and is rated at 0.5A per output. One OBM-4 module will be required for every eight MTP outputs that are to be converted to active high operation. Up to four OBM-4s can be used with an MTP-7 and up to eight with an MTP-8.
