| Part Number: | ERS | - | 32 | LC |
|---|---|---|---|---|
| Explanation: |
Series ERS - Normally open relay outputs with grouped common terminals |
Channels 04 - 4 relay channels; TC input only |
Input TC - Terminal input; 04, 08 or 16 channels |
These six ERS modules use normally open relay contacts, with one output common for each group of four channels. TC models have terminal inputs; LC models have MIL connector inputs. Outputs use terminal connections. The input circuit includes surge absorption and incorrect-connection protection, and the relays use pluggable bases.

| ERS-08TC | 8 | 2 × 4 channels | 64.5×55mm | |
| ERS-08LC | 10-contact MIL | |||
| ERS-16TC | 16 | 4 × 4 channels | Terminals | 117.5×55mm |
| ERS-16LC | 20-contact MIL | |||
| ERS-32LC | 32 | 8 × 4 channels | 40-contact MIL | 150×80mm |
| Property | Value and condition |
|---|---|
| Rated coil voltage | 24VDC±10% |
| Rated coil current | Approximately 7.6mA per relay |
| Initial pickup voltage at 20°C | Less than 70% of rated coil voltage |
| Initial release voltage at 20°C | More than 5% of rated coil voltage |
| Operate time | Less than 10ms at 20°C and initial rated voltage, excluding contact bounce |
| Reset time | Less than 5ms at 20°C and initial rated voltage, excluding contact bounce and without a diode |
The 7.6mA value is an individual-coil specification, not the total current of a populated module. The six listed configurations are 24VDC versions; other voltage variants are not assigned here.
The contact-capacity and maximum-power entries are inconsistent at the same stated load voltages. They are retained below as listed data; a verified maximum switching envelope has not been established. In particular, 5A at 250VAC exceeds 750VA, and 5A at 30VDC exceeds 90W. Do not combine these entries into a confirmed operating rating or infer an updated relay specification.
| Per-relay entry | AC | DC |
|---|---|---|
| Listed resistive contact capacity, unverified against power limit | 5A at 250VAC | 5A at 30VDC |
| Listed maximum resistive switching power | 750VA | 90W |
| Listed maximum contact voltage | 250VAC | 30VDC |
| Listed maximum contact current | 5A; applicability with the stated voltage/power combinations remains unresolved | |
| Minimum applicable load | Unspecified | 1mA at 5VDC, reference value |
| Test condition | Listed life |
|---|---|
| Mechanical, 180 operations per minute | More than 20 million operations |
| Resistive, 3A at 250VAC | More than 30,000 operations |
| Resistive, 3A at 30VDC | |
| Resistive, 2A at 250VAC | More than 100,000 operations |
| Resistive, 2A at 30VDC |
Life-test points do not establish the unresolved maximum switching rating. Common-terminal aggregate current is unspecified and must not be inferred by multiplying the per-relay entry by four.
| Channel count | Output common assignment |

Channel labels above use hexadecimal notation where letters appear. TC inputs use COM and channel terminals; LC inputs include VCC, GND and channel contacts. Input supply/common terminals and output contact commons serve different functions.
| LC model | Connector contacts | Supply positions | Signal positions |
|---|---|---|---|
| ERS-08LC | 10 | 1 VCC; 6 GND | 2–5: channels 0,2,4,6; 7–10: channels 1,3,5,7 |
| ERS-16LC | 20 | 10 VCC; 20 GND | 1–8: channels 0–7; 11–18: channels 8–F; 9 and 19 unassigned in the diagram |
| ERS-32LC | 40 | 19 and 20 VCC; 39 and 40 GND | Use the exact connector orientation and cable pin assignment for all 32 signals; do not extrapolate the 10-contact mapping |
The indicated terminal conductor limit is 1.5mm², with AWG16 listed alongside it. These nominal sizes are not exact conversions; check the chosen wire and terminal fit. Match the PLC-specific cable, signal definition and connector orientation. Module height, terminal strip length, ambient limits and fitted relay part number are unspecified.
