Features:
- Eight isolated relays: Form A contacts switch separate AC or DC circuits
- Electromechanical operation: 10 ms response and a 0.3 Hz switching limit govern use
- Load-specific ratings: contact current depends on voltage and load type
1794-OW8 is chosen when a FLEX I/O station must switch circuits that benefit from dry, individually isolated relay contacts.
Mechanical contact life and switching rate make duty cycle a primary selection question, particularly for coils or repetitive outputs.
A durable installation documents circuit voltage, load category, suppression, fuse, terminal base, and isolation method for all eight channels.
Availability of 1794-OW8 is subject to Apter Power inventory and sourcing confirmation.

Relate switching duty to mechanical contacts
- Frequency: keep operation at or below 0.3 Hz.
- Life: use the published minimum operation count with the actual load category.
- Timing: allow for 10 ms turn-on and turn-off behavior.
- Duty record: capture cycle rate and energized duration for each output.
Apply the correct rating to each external circuit
- AC load: compare voltage, current, and power factor with the relay rating.
- DC load: use the specific current limit for the circuit voltage.
- Inductive load: provide approved suppression and assess release energy.
- Fuse: protect each circuit with the documented external approach.
Keep isolated circuits correctly separated
- Compatible bases: confirm the approved TB2, TB3, TB3S, TBN, or TBNF option.
- Energy sources: identify every external AC and DC supply.
- Conductor labels: map contacts, loads, and returns point by point.
- Service isolation: prove all hazardous circuits are de-energized before removal.
Officially supported application roles
- Isolated switching: operate separate supported AC or DC field circuits.
- Interposing duties: control contactors or relays within the published load limits.
- Low-frequency actuators: switch devices whose duty respects mechanical relay life.
- Mixed-voltage panels: maintain documented circuit separation across isolated contacts.
