IQS900 Signal Conditioner Upgraded & Backward‑Compatible Replacement for IQS450

The proximity measurement chains signal conditioner is newly upgrade from IQS450(with the part number (204-450-000-002) to IQS900 (with the part number 204-900-000-011). Additionally, IQS900 signal conditioner is backward compatible replacement for IQS450.

Besides cosmetic modifications in appearance, this upgrade brings significant technical improvements to the module itself. One notable feature that sets the IQS900 apart from the IQS450 is its integrated diagnostic function. The diagnostic can detect the circuit in the sensor, integral cable and extension cable, the component defects in the system as well as the voltage on the power supply. IQS900 with diagnostics are SIL 2 , suitable for use in hazardous site.

Key Features:
Enhanced reliability
Low significant risk
Compliant with EC 61508 and Cat 1 PL c in accordance with ISO 13849.
Optional diagnostics
Backward compatibility with the IQS450
Compliant to API670 ed. 5th
Certificate for multiple EX
The raw voltage signal is accessible from the “RAW” pin without device disconnection.
Configurable sensitivity and measuring range

Ordering number:
The IQS900 and IQS450 are the configurable products. When ordering a signal conditioner, the ordering number is necessary, and the ordering number are used to specify the configuration of the device. The below form shows the difference between IQS900 and IQS450 ordering number.

Replacing the IPC704 Signal Conditioner with the New IPC707

IPC707 244-707-000-012 is designed as a signal conditioner, it has replaced the IPC704 244-704-000-042 since the year of 2019.  IPC707 can totally match and even better of the IPC704.

There are below improvements for IPC707:
▪ A new filter compliant with ISO 2954, independent of transmission gain and input impedance
▪ A new grounding concept to improve immunity to rack voltage disturbances
▪ Lower output impedance for long-distance voltage signal transmission
▪ Optional diagnostic circuitry (i.e., Built-In Test Equipment, BITE) that provides continuous feedback on the health of the measurement chain (sensors, cabling, and the IPC707 itself)
▪ For functional safety applications: It meets SIL 2 per IEC 61508, as well as PL c Cat 1 per ISO 13849.
▪ New DIN rail mounting adapter and detachable screw terminal connectors for easier installation.

IPC707 enhance the performace of the IPC704, then how to replace IPC704 to the new upgrade signal conditioner IPC707?

1. Removing the IPC704 Signal Conditioner:
(1) Power off the device completely to ensure safety.
(2) Open the access door or remove the cover of the industrial housing.
(3) Label every wire of the sensor cable (on the "sensor side") and the transmission cable (on the "monitor side," both connected to the IPC704)
(4) On the IPC704, loosen the screw terminals located on the left or bottom of the unit to disconnect the sensor cable from the "sensor side" circuit.
(5) On the IPC704, loosen the screw terminals located on the right or top of the unit to disconnect the transmission cable from the "monitor side" circuit (electronic monitoring system).
(6) Detach the cables from the cable glands (packing gland covers) on the industrial housing.
(7) Remove the IPC704 from its mounting position on the equipment plate or DIN rail.

2. Installing and connecting the IPC707
(1) Make sure the equipment is fully powered down.
(2) Continue using the original industrial housing or fit a new one.
(3) Install the IPC707 into the industrial housing.
(4) Trim or extend the sensor cables and transmission cables to the proper length where required.
(5) Loosen the cable glands on the ABA17x industrial enclosure, then thread the cables through the openings.
(6) Strip about 5 millimetres of insulation from each wire end to expose the inner conductor.
(7) When connecting each wire:
▪ Confirm the corresponding screw terminal and terminal block on the IPC707 for each wire.
▪ Insert the exposed conductor into the designated terminal, then fasten the screw tightly to secure the connection.

3. Configuring the external monitoring system
(1) When swapping IPC704 for IPC707 in CPxxx pressure measurement chains, update all connected external monitoring and protection systems.
(2) Set these systems to apply the standard nominal deviation values of the IPC707
(3) Values represent the diagnostic component (DC) within the IPC707 output signal.
