CON020/91 Signal Conditioner Module Driver | Epro

Configured for signal conversion in rotating machinery monitoring networks, the Epro CON020/91 (CON020/91 Signal Conditioner Module Driver) provides direct physical electrical execution for processing transducer inputs into standardized analog signals. The module accepts raw probe inputs and delivers either analog voltage or 4-20 mA current outputs, interfacing directly with TSI monitoring platforms to support continuous data acquisition in machinery protection applications.

Hardware Specifications

Mechanical Monitoring and TSI Characteristics

The CON020/91 module is engineered to manage critical signal parameters for eddy-current probe scaling within machinery protection systems. It supports the precise adjustment of gain and offset required for gap voltage validation against -10 VDC targets, ensuring that the sensor response remains linear across the transducer's measurement range. To preserve data integrity in high-density rack configurations, the module incorporates internal cross-talk suppression and EMI immunity filters, which are required for reliable rotor dynamics analysis under varying load and speed conditions.

Frequently Asked Questions (FAQ)

Q: Can the CON020/91 be hot-swapped while the machinery is operating?

A: Module removal or replacement during active operation depends on the backplane architecture and system configuration. Ensure the I/O channel is inhibited in the monitoring software to prevent a false trip or alarm signal before extracting the module.

Q: Is the 4-20 mA output isolated from the power supply ground?

A: The module is designed for industrial integration where loop isolation is required. Consult the system interconnection diagram to confirm if the output stage requires an external isolator to prevent ground loops between the module and the destination input card.

Field Installation Guidelines

1. Mount the module on a standard DIN rail or designated rack chassis, ensuring the mechanical locking clip is fully engaged.
2. Terminate signal input cabling using shielded, twisted-pair wire to minimize electromagnetic interference (EMI) ingress.
3. Verify that the shield drain wire is bonded to the cabinet earth ground at the rack entry point only to avoid ground loops.
4. Set the internal jumpers or configuration switches to match the desired output mode (voltage or current) before applying 24 VDC power.
5. Confirm stable signal output at the terminal block using a calibrated multimeter prior to validating the sensor gap voltage at the probe tip.
