The DWYER 15011 is a precision temperature controller featuring solid-state relay (SSR) output with 3.5A capacity at 240VAC maximum. It offers high accuracy of 0.25% of span ±1 least significant digit. The unit includes a single-pole single-throw (SPST) relay rated at 3A resistive, 1.5A inductive @250VAC, with pilot duty capacity of 250VA (2A@125VAC or 1A@250VAC). Designed without alarm functionality, this industrial-grade controller maintains stable performance at typical operating temperature of 25°C (77°F).
