产品描述

Inputs LCA15变送器通用型称重变送器多种输出模块（电压/电流/数字）可供选择输入灵敏度范围0.5-200mV 10V，160mA激励，至多可驱动6只350欧姆传感器 6线制连接用于远距离补偿全隔离4-20mA和0-10V输出 2个固态继电器设定点输出 AC/DC供电可选数字显示编程板透明ABS/铸铝外壳可选
The input is of the Load Cell/Strain Gauge type. With transducer excitation voltage of 9.6 volts @ 160mA to drive 6 x 350R bridges
Compensation by ± sense wires for cable and safety barrier losses down to 3V excitation
Load cell sensitivity is preset via DIL switches to 0.5, 0.8, 1.0 1.25, 1.5, 2.0, 2.5, 3.5, 5, 10, 20, 50, 100 or 200mV/V
Initial offset is no greater than ± 0.15mV (15uV/V) which is cancelled during auto calibration
Speed	is 10 readings per second with a digital filter to reduce speed
Accuracy	is 90 days ± 0.08% of reading, +/- 0.05% FSD being typical
Drift	is 0.002% per degree C @ 2.5mV/V typical
Resolution	15 bit/ 4.5 digits
Contact inputs	are available for auto tare, print and peak hold reset and are volt free
Analogue Outputs
Drive	4-20mA up to 1Kohm and 0-10 volts up to 2mA
Accuracy	4-20mA + 0.15% of range, typical. 0-10V ±2% before calibration
Resolution	as for display up to 13 bits/4.5 digits. Settling time 350mS to within 1% of step change
Isolation	±130V RMS or DC max to analogue input or any other port
Power Supplies
LS1	110V-120V AC or 220/230V AC 50-60Hz 10W
LS3	9-32V DC 10W isolated
Data Retention/Protection
Retention	10 years for set up values, minimum of 100,000 write cycles
Protection of data and function(s)	Watchdog timer giving repeat auto resets. Impending power detection and hold off. Keypad security and time out
Other Options & Accessories
