Honeywell 900H01-0102 Relay Output Module

Frequently Asked Questions (FAQ)

Q1: Does the module provide isolation between relays?
A1: Yes, each relay contact is isolated from others and from logic circuitry.

Q2: What is the maximum current load per relay output?
A2: 4A for resistive loads and 0.5A for incandescent lamps at 240VAC or 30VDC.

Q3: Is hot swapping supported?
A3: Yes, the module can be inserted or removed while the controller is powered, but field terminal block power should be disconnected first.

Q4: Are fuses included in the module?
A4: No, fuses are not included. External fusing at the field device is recommended.

Q5: Are there LED indicators for channel status?
A5: Yes, each output channel has a green LED that indicates when the channel is ON.

Q6: What types of loads can this module drive?
A6: It can drive resistive and incandescent lamp loads. For inductive loads, external protection is needed.

Q7: What is the switching response time?
A7: OFF to ON is up to 11 ms, and ON to OFF is up to 8 ms.

Q8: What is the expected service life of the relay?
A8: Mechanical life is rated at 50 million cycles, and electrical life at 100,000 operations depending on load type.
