Description

. . . . . The Johnson Controls A19ABC-73C is an A19 Series remote bulb temperature control with SPDT contacts, a range of 40 to 90°F, an adjustable differential of 3 to 12, a 3/8 in. x 6 in. bulb on a 6 ft. capillary, in a NEMA 1 enclosure.

The 6 in. bulb is the longest sensing element in the A19ABC group, where 3, 3-1/2, 4 and 5 in. bulbs are the norm. Extra bulb length increases the sensing surface, which averages temperature over a greater span - that steadies the control against local air movement or stratification and is particularly useful on a narrow 40-90°F range where a short bulb reacting to a local draught could cause unnecessary cycling.

The 40-90°F band is comfort and above-freezing cooling territory: conditioned space, coolers, water loops and process baths held near room temperature. SPDT contacts give changeover - a rise above setpoint opens red-to-blue (R-B) while closing red-to-yellow (R-Y) - so one control can serve heating and cooling outputs or stop one device while starting another. The 3 to 12 adjustable differential is set in the field via an internal scale plate marked in increments, shipped at the minimum setting stamped on the control.

Sensing is by a liquid-filled element with repeat accuracy unaffected by barometric pressure or cross-ambient conditions, and switching is by a Precision Pennswitch unit with snap-acting, dust-tight contacts. Wide-range adjustable-differential ratings apply: 16.0 FLA / 96.0 LRA at 120 V, 9.2 / 55.2 at 208 V, 8.0 / 48.0 at 240 V, 22 A non-inductive at 120 to 277 VAC (SPDT normally-closed contact 16 A), 125 VA pilot duty at 24 to 600 VAC.

For comparison, the fixed-differential A19AAF-21C covers the same 40-90°F range with a 5-3/4 in. bulb but a fixed 1-1/2 F° differential and only a 10 A non-inductive rating - so this model is the adjustable, higher-current alternative for the same temperature band. The differential is published without a unit.. Johnson Controls. Johnson Controls. A19ABC-73C.
