Inputs
| Parameter | Value |
|---|---|
| Power Consumption | 3.2 Watts typical |
| Signal | Accepts up to two transducer signals from proximity probe transducers or magnetic pickups. Input signal range: +0.8 V to -21.0 V (Non-Isolated I/O modules). Signals exceeding this range are limited internally. Passive magnetic pickups require shaft rotative speed > 200 rpm (3.3 Hz). |
| Input Impedance | 21.8 kΩ minimum |
Signal Conditioning
| Parameter | Value |
|---|---|
| Speed/Frequency Signal Ranges | Input: 1 to 1,200,000 cpm (0.017 to 20 kHz). Supports multiple events per revolution to a maximum of 20 kHz. Output: 1 to 99,999 cpm (0.017 to 1667 Hz). |
| Speed/Frequency Signal Accuracy | At +25°C (+77°F): Non-processed signals: 0.017 to 100 Hz: ±1 cpm; 101 to 500 Hz: ±8 cpm; 501 to 20 kHz: ±1% of cpm. Processed signals: 0.017 to 60 Hz: ±1 cpm; 61 to 150 Hz: ±8 cpm; 151 to 20 kHz: ±1% of cpm. |
Transducer Conditioning
| Parameter | Value |
|---|---|
| Auto Threshold | Minimum signal amplitude for triggering: 2 V peak-to-peak. Minimum frequency: 120 rpm (2 Hz). |
| Manual Threshold | For inputs above 0.017 Hz (1 rpm for 1 event per revolution). User-selectable from 0 to -20 Vdc. Minimum signal amplitude for triggering: 500 mV peak-to-peak. |
| Hysteresis | User-selectable from 0.2 to 2.5 V. |
Outputs
| Parameter | Value |
|---|---|
| Buffered Keyphasor Signals | Two buffered Keyphasor outputs available at the front of the rack via coaxial connectors. Two buffered Keyphasor outputs available at the back of the rack via Euro Style connectors. |
| Output Impedance | 504 Ω maximum buffered output impedance. |
| Keyphasor Transducer Power Supply | -24 Vdc, 40 mA maximum per channel. |
Front Panel LEDs
| Parameter | Value |
|---|---|
| OK LED | Indicates when a fault has been detected in the Keyphasor Module. |
| TX/RX LED | Indicates when the Keyphasor Module is communicating with the Rack Interface Module (RIM). |
