Note:
1.Model numbers with "L" have a maximum counting speed of 30 Hz (cps). Other models are 1 kHz (cps). Only the models with a 20-Hz maximum counting speed have multi-voltage inputs.
2.The bottom row gives recommended substitute products or models with substitute functions. For details, refer to the following information.
2.The substitute product in column (1) is H7EC-N.
If a wire-wrap terminal was used, Y92S-37 Wire-wrap Terminals (two in one set) must be separately purchased and attached to the terminal block.
If manual reset is not used, the key-protect switch must be set to ON.
If the maximum counting speed was 1 kHz (cps), the counting speed switch must be set to 1 kHz (cps).
3.The substitute product in column (2) is H7EC-NV.
If a wire-wrap terminal was used, Y92S-37 Wire-wrap Terminals (two in one set) must be separately purchased and attached to the terminal block.
If manual reset is not used, the key-protect switch must be set to ON.
If the maximum counting speed was 1 kHz (cps), the counting speed switch must be set to 1 kHz (cps).
4.The substitute product in column (3) is H7EC-NFV.
If the high level was 6 to 24 VDC, H7EC-NV with DC voltage input must be used because if the DC high level of H7EC-FBV with multi-voltage input was 6 to 240 VDC, it becomes 24 to 240 VDC for H7EC-NFV.
If a wire-wrap terminal was used, Y92S-37 Wire-wrap Terminals (two in one set) must be separately purchased and attached to the terminal block.
If manual reset is not used, the key-protect switch must be set to ON.
5.There are two substitute products in column (4). The substitute product for H7EC-P is H7EC-NP, and H7EC-NLP for H7EC-LP because Totalizers with direct mounting on the PC board do not have the counter speed switch.
6.General Comparison of H7EC and H7EC-N
| Compared item | H7EC | H7EC-N | Remarks |
| Number of digits | 6/7 | 8 | |
| Character height | 6.7 mm | 8.6 mm | |
| Input signal level | DC voltage input High level: 4.5 to 30 VDC Low level: 0 to 2 VDC Multi-voltage input High level: 24 to 240 VAC/6 to 240 VDC Low level: 0 to 1.5 VAC/0 to 2 VDC |
DC voltage input High level: 4.5 to 30 VDC Low level: 0 to 2 VDC Multi-voltage input High level: 24 to 240 VAC/VDC Low level: 0 to 2.4 VAC/VDC |
See note 1 |
| Reset system | Non-PCB mounting model: Reset - Glossary of Industrial Automation">External reset only, external/manual reset PCB mounting model: Power-OFF reset: 100 ms min. |
Non-PCB mounting model: External/Manual Reset (manual Reset system has key-protect switching) PCB mounting model: Power-OFF reset: 500 ms min. |
See note 2 |
| Battery replacement | Not possible | Possible (except for PCB mounting models) |
Note:
1.The high level 6 to 24 VDC of H7EC-N is cut, so choose a DC voltage input model.
2.Be careful when using the power-OFF reset.
