[Features]
· Economical, with unbeatable ease-of-use.
· Operation is simple, with an increase key for each digit. Safe and reliable.
· Insulated separation of the power source circuit from the input circuit for parts inside the counter.
· An upper limit of the setting value can be set, preventing mis-operation by the output apparatus due to erroneous setting.
· The function counting the number of outputs contributes to estimating counter lifetime and loading
· Water resistant/dust resistant structure (UL 508 Type 4X: IP66).
· Implements a key protect function.
H7CZ external appearance
Excellent operability
Operation is simple, just press the up key for each digit.
Setting value limit function
An upper limit for the setting value can be set, preventing unexpected operation by the output apparatus due to erroneous setting.
Insulated separation of the power supply and input circuit
The power supply circuit and input circuit are isolated from each other in the timer.
Non-insulated counters have constraints on wiring such as prohibiting grounding of the input 0 V line, etc., and if there are errors in the wiring the counter will fail, but the H7CZ is secure.
Number of outputs counting function
The number of times output is turned ON is cumulatively counted (alarm display, number of times can be monitored, units of 1,000). Contributes to estimation of the counter and load life.
Waterproof / dust-proof structure (UL508 Type 4X: IP66)
Can be used safely even in areas with water.
Note: When using waterproof packing Y92S-29.
Implementation of a key protect function
7 patterns can be selected. Can be set to match the usage situation.
