The Allen-Bradley 1771-HRA Resolver Excitation Module is designed for the 1771 I/O chassis slot and functions with the IMC 120 System to deliver precise Sine and Cosine signals for resolver feedback. Utilizing the 1771-PS7 power supply, this module operates at a backplane power consumption of 0.4W and includes a green LED for power status indication. With minimum and maximum sinusoid output amplitudes of 6.72V and 7.42V RMS respectively, it ensures accurate position feedback, featuring a maximum Sine-Cosine matching amplitude of 0.3%, a Sine Phase OFFSET of 0.450, and a signal frequency of 2.5 KHz.
