Bitronics M87x Family Bitronics D/3 ® Orion S10, S11, S12 Signal Input Modules Key Features • Supports various system configurations • 4 ac currents up to 100A RMS (S10), 20A RMS (S11) or 4A RMS (S12) • 10 voltages for up to 600V peak to ground • Ideal for bus-tie or tie-line breakers and cap banks S10, S11, S12 Signal Input Modules The current signals are transformer coupled, providing a true differential current signal. Internal current signal wiring is designed to ensure CT circuit integrity. All voltage inputs are measured relative to a common reference level (ground). Calibration constants for variations in input circuits are stored in non-volatile memory with readable checksums. Applications • Operates with fundamental signal frequencies from 15 to 70Hz • Supports 2, 2 ½, or 3 element connections • Suitable to operate from potential transformers at 69 or 120V taps • Also suitable for direct connection to 240/208/120Y, 480/277Y, or 600/347Y systems • Supports generator bus-tie breakers, tie-line breakers, or capacitor bank applications with 2 sets of 3-phase voltage inputs • Suitable to operate from current transformers with 1A ac or 5A ac outputs • Neutral can be measured directly from a current transformer or as a residual neutral current • Suitable for monitoring dc station battery voltage AC Current Inputs • S10 - Four inputs, each at 5A ac nominal, linear to 100A ac symmetrical (141A peak) at all rated temperatures • S11 - Four inputs, each at 1A or 5A ac nominal, linear to 20A ac symmetrical (28A peak) at all rated temperatures • S12 - Four inputs, each at 1A ac nominal, linear to 4A ac symmetrical (5.7A peak) at all rated temperatures • Withstands 400A ac for 2 seconds. Minimum 2500 V ac isolation • 12AWG SIS 600V internal wire, crimped ring-lugs with brazed seams, and bolted connections • Burden < 0.04VA @ 5A ac Voltage Inputs • Eight inputs read to 600 V peak to case (ground). For use with one or two independent 3-phase systems, either 3 or 4-Wire • Two inputs read to 600 V peak to case (ground). For use with ac or dc signals. Suitable for monitoring dc station batteries • Withstands 5kV rms, 1 minute, input to case (ground); 2kV rms, 1 minute, input to input • Burden >7 Mohms differential and to ground Output • 14 signal to ground analog measurements • Self-aligning 24-pin header to connect measurements to analog processor Front Panel Features • 10-32 terminals for current inputs • Removable voltage input terminal blocks accept terminal lugs up to 0.250” (6,35mm) wide for CE version and 0.325” (8,25mm) wide for non-CE version Environmental • -40C to +70C operating temperature • 0-95% non-condensing relative humidity • IC III (Distribution Level), Pollution Degree 2 Installation category Bitronics M87x Family S10, S11, S12 Signal Input Modules M871 2-Element, 3-Wire, DELTA Connection M871 2½-Element, 4-Wire, WYE Connection M871 3-Element, 4-Wire, WYE Connection Copyright © 2010 NovaTech, LLC.
