Product Description:

The model HZ170A601 is an electromechanical reset counter designed for precision count control. It features a front mounted adjustable set point and operates within count range of 2 to 100. The counter functions with high speed counting and zero reset capability on power failure.

This HZ170A601 Reset Counter incorporates a solenoid driven pawl feed motor and an electromechanical clutch to ensure reliable and accurate operations. A front knob allows users to set the desired count point. The count progresses in a clockwise direction that is indicated by a visible pointer. It includes two sets of SPDT instantaneous contacts and two delayed SPDT switches. The delayed switches activate once the count reaches zero. The instantaneous and delayed outputs can be interconnected for advanced sequence control. The reset counter supports a maximum speed of 500 counts per minute with 100 % accuracy. The reset time is approximately 500 milliseconds at full count. The input for the stepping motor requires 40 ms “ON” and 80 ms “OFF” time while the clutch coil requires 50 ms pull in time. This allows consistent and smooth operation during high speed processes. The reset counter’s flexible output configuration, adjustable range and high speed capacity make it versatile.

The HZ170A601 reset counter by Danaher is housed in a CYCL-FLEX® standard case for compatibility and durability in various industrial environments. The counter is ideal for applications demanding fast, accurate and repeatable counting operations. It ensures consistent performance with low latency between reset and operation. Its electromechanical nature makes it suitable for rugged environments where electronic counters may fail. The robust design of this reset counter’s motor and clutch mechanism ensures durability under repeated use.
