Frequently Asked Questions (FAQ)

Q1: What is the primary function of the 163179-03?

It is the main board for the 3500/62 Process Variable Monitor. It accepts 4-20 mA current or ±10 Vdc voltage inputs from industrial transmitters, conditions these signals, and compares them against user-programmable alarm setpoints (Alert and Danger). It monitors non-vibration parameters such as pressure, flow, temperature, and level.

Q2: What I/O modules are compatible with the 163179-03?

The 163179-03 works with multiple rear I/O module variants: 136491-01 (±10 Vdc, internal terminations), 136499-01 (±10 Vdc, external terminations), 136294-01 (isolated 4-20 mA, internal terminations), 136483-01 (isolated 4-20 mA, external terminations), and 137110-01 (4-20 mA with intrinsic safety barrier, internal terminations).

Q3: Can the 163179-03 be used in a Triple Modular Redundant (TMR) configuration?

Yes. For TMR applications, three identical 3500/62 modules must be installed adjacent to each other in the rack. The system uses two types of voting to ensure accurate operation and avoid single-point failures.

Q4: Is the 163179-03 hot-swappable?

Yes, the module supports hot-swap capability. However, during replacement, the six-channel process-variable measurement is temporarily invalid while other rack modules continue running normally. Before pulling or inserting the module, bypass active alarms to avoid accidental machine trips.

Q5: What is the difference between the 3500/62 and the 3500/60/61?

The 3500/62 is a Process Variable Monitor for pressure, flow, temperature, and level signals (4-20 mA / ±10 Vdc). The 3500/60 and 3500/61 are Temperature Monitors for RTD and thermocouple inputs. The 3500/61 provides recorder outputs (4-20 mA retransmission) per channel, while the 3500/60 does not. Main boards and I/O modules cannot be swapped between these monitor types.
