H8GN Pre-set countersWorld’s smallest compact preset counter/timerThe H8GN is a 1/32 DIN timer and counter in one. It is simple to switch between the timer and counter functions. During operation it is also possible to switch the display to monitor the totalising count value in 8 digits. Many sophisticatedfunctions comeas standard with H8GN.• Size in mm (H×W×D) 24×48×83, 1/32 DIN sizehousing• 8 digit display, 4 value and 4 set value• Front mounting• –999 to 9999• 24 VDCOrdering informationFunctions Supply voltageOutputOrder codeCommunicationsCounter TimerNo communicationsRS-485Counter: Up/down/reversible,4 digits,N, F, C or K output modesTotal counter: 8 digitsA: ON-delayB: FlickerD: SignalOFF-delayE: IntervalF: AccumulativeZ: ON/OFF-duty adjustable flicker24 VDCContact output (SPDT) H8GN-ADH8GN-AD-FLKSpecificationsRated supply voltage24 VDCOperating voltage range85 to 110% of rated supply voltagePower consumption 1.5 W max.
