71M6541D/F Using Local Sensors
Figure 35 shows a 71M6541D/F configuration using locally connected current sensors. The IAP-IAN
current channel may be directly connected to either a shunt resistor or a CT, while the IBP-IBN channel is
connected to a CT and is therefore isolated. This configuration implements a single-phase measurement
with tamper-detection using one current sensor to measure the neutral current. This configuration can
also be used to create a split phase meter (e.g., ANSI Form 2S). For best performance, both the IAP-IAN
and IBP-IBN current sensor inputs are configured for differential mode (i.e., DIFFA_E = 1 and DIFFB_E =
1, I/O RAM 0x210C[4] and 0x210C[5]). The IBP-IBN input must be configured as an analog differential
input disabling the remote sensor interface (i.e., RMT_E = 0, I/O RAM 0x2709[3]). See Figure 2 for the AFE
configuration corresponding to Figure 35.
