The GEL 104 counter is a counter / position display in a compact DIN 96x48mm housing. It features an LED display showing presets or actual counts. For output 1 and output 2, a relay output with change-over contacts are available. Terminals for external reset, inhibit, hold and keylock integrated. Several counting modes are possible. The count input can be interpolated (or multiplied) with a factor of 1, 2 or 4, thus increasing accuracy. An internal multiplier can scale the actual count input to units, e.g. inches or millimetres. The five buttons on the counter allow for easy use by the operator.
