The PA 11 is a 1-channel photoelectric amplifier to be used with 1 set of remote sensors.
The Telco remote transmitter (LT) and receiver (LR) sensors in combination with the Telco Photo Amplifier PA 11 will operate problem free through steam, oil, grease, water, fog, dirt and most other contaminations that would cause ordinary infrared sensors to fail.
The PA 11 T has improved features and performance. Based on the latest microprocessor technology with full gain control, on-off time delay, signal level indication and a supply voltage ranging from 24 V ac/dc to 115 V ac and 230 V acv, the microprocessor controlled Photo Amplifier continuously surveys both the remote transmitter and receiver. If the cable to a sensor breaks, or if a sensor has an internal electrical failure, two individual LEDs on the front of the Photo Amplifier – one for the transmitter and one for the receiver – will clearly indicate the failing one, making replacement fast and easy and reducing service costs to a minimum.
