The BL101P (single bar) BL202P (dual bar) features a barrier strip connector that accepts spade or closed loop connector lugs is standard. Detachable terminal block connectors are optional and can be specified at time of order. For control applications, the optional set point/relay module provides on/off and differential gap control and annunciation using three set points and two Form-C relays per input. The optional digital display reads to 10% over and under range. The optional temperature measurement module makes the instrument a direct-reading indicator for E, J, K, and T thermocouples or 100-ohm RTD, and an optional retransmission module simplifies distribution of the temperature parameter throughout the system.

It is a direct replacement for the Sigma 9270 non-DIN instrument. This simplifies retrofit into existing systems without panel modifications.
