Combined I/O Functionality in the NR1JY-08R07DT
The NR1JY-08R07DT merges digital input and relay output capabilities within one compact MICREX-F module. Field devices connect directly to this unit, which then interfaces with the PLC backplane. Engineers choose it for automation projects where panel space remains limited.
Signal Specifications and Channel Configuration
Eight input points accept 24 V DC signals, while seven output points employ relay contacts. Input current draws 7 mA per point, and each output relay handles 2 A resistive loads. Furthermore, optocoupler isolation protects input circuits from field transients.
| Parameter | Specification |
|---|---|
| Input Points | 8 (24 V DC) |
| Output Points | 7 (relay) |
| Input Current | 7 mA per point |
| Output Rating | 2 A per point (resistive) |
| Isolation | Optocoupler / relay |
Physical Dimensions and Component Layout
The module measures 105 mm wide, 85 mm high, and 60 mm deep. Its weight reaches approximately 320 grams. Additionally, one main PCB carries the input circuits alongside seven relays. Small capacitors filter input signals for each channel.
| Parameter | Specification |
|---|---|
| Width | 105 mm |
| Height | 85 mm |
| Depth | 60 mm |
| Weight | ~320 g |
| Relays | 7 |
Installation and Status Indication
A removable terminal block sits along the bottom edge for convenient wiring access. Green LEDs indicate active input channels, while red LEDs show output status. Consequently, technicians can verify field connections without external test instruments. The NR1JY-08R07DT draws power from the backplane bus, eliminating separate logic supplies.
