IO-DIMDigital Input MultiplexersThese modules are intended for use with BMScontrollers to expand their input capacity bymultiplexing four or six digital signals, or 4or 6 x 24Vac/dc inputs into a single analoguecontroller unit. Each combination of inputstates corresponds to an analogue valuefrom the IO-DIM4 and IO-DIM6 which can bedecoded into four or six digital status bits.FEATURES■■Fault finding LED indication■■Input status indication■■Input status simulation■■Expands controller input capacity■■Self calibrating outputSPECIFICATIONInputs:VFC, 24Vac or 24VdcOutputs:0-10Vdc into 2kΩ impedance4-20mA into 500Ω max.Power supply:24Vac ±15% @ 50Hz or24Vdc +15% – 6%Current:35mA max. voltage output mode55mA max. current output modeLED indication: Supply OK, supply voltage low, supply voltage high,current output (4-20mA output only)Ambient range: Temperature –10 to +50°C (14 to 122°F)RH0 to 80% non-condensingDimensions: IO-DIM4 75 x 55 x 42mm (2.95 x 2.17 x 1.65”)IO-DIM6 75 x 75 x 42mm (2.95 x 2.95 x 1.65”)Weight: IO-DIM4 80g (0.18 lb)IO-DIM6 100g (0.22 lb)Part code DescriptionIO-DIM4 4 x VFC or 24Vac/dc inputs, selectable outputIO-DIM6 6 x VFC or 24Vac/dc inputs, selectable outputData sheets: IO-DIM4.pdf ∙ IO-DIM6.pdfVolume Price Breaks are applicableUnit Price (10+)IO-DIM4Please see price listIO-EPCElectro-pneumatic ConvertersIntended for use with BMS controllers toconvert an analogue electrical controlsignal (either voltage or current loop) to aproportional pneumatic output.
