The Telco Sensors PAB series are “BUS” photoelectric amplifier modules engineered to work with remote photoelectric sensor pairs (LT transmitters and LR receivers) for industrial object detection, presence control, and material handling applications. These amplifiers accept amplified optical signals and provide adjustable timing, output switching, and diagnostic feedback, making them suitable for integration into control systems that require multiplexed or independent channel outputs.
The PAB series supports a range of amplifier configurations including a single channel (PAB 10 A 209) and dual‑channel (PAB 20 A 009) models with removable screw terminal connections. The PABA 30 A 209 adds automatic gain adjustment for each channel, allowing continuous compensation for moderate misalignment or contamination without manual intervention. All models operate on 10‑30 V dc or 24 V ac supply, offer adjustable on‑off delay timing, and include multiple LED indicators for power, output status, alarm, and sensor feedback.
