Adjustable Dry Contact Dosing Relay
The BL983327 features a dosing relay that is activated when the reading is above a user programmable set point.
Programmable Overdose Protection
For enhanced safety the mini controller can be programmed to deactivate the dosing relay if the set point is not reached within a specified time interval. The overdosing timer is programmable from 5 to 30 minutes or disabled.
Relay Control Override
With the flick of a switch the mini controller's relay can be disabled (Off), placed in control (Auto), or be activated for manual operation (On) which is useful for priming a dosing pump.
Multicolor LED Indicator
Multicolor LED indicator allows an operator to quickly check the status of the controller.
-
Green = Meter in measurement mode and reading is below the set point.
-
Orange/Yellow = Reading is above the set point and the relay is active.
-
Blinking Red = Indicates an alarm condition such as when the maximum dosing time has been exceeded.
Fuse Protected Dosing Contacts
The relay dosing contact is rated for up to a 2A load and is fuse protected.
Labeled Termination Connections
Quick-connect terminal blocks are clearly labeled for easy connection to power, conductivity probe and relay that can be used to operate a dosing pump, valve, audible alarm, or light.
Hanna BL983327-1 电导率迷你控制器
可调干触点计量继电器
BL983327 具有一个剂量继电器，当读数高于用户可编程设置点时，该继电器被激活。
可编程过量保护
为了增强安全性，如果在指定的时间间隔内未达到设定点，则可以对微型控制器进行编程以停用计量继电器。过量计时器可编程为 5 到 30 分钟或禁用。
继电器控制覆盖
通过轻按开关，可以禁用（关闭）微型控制器的继电器、置于控制状态（自动）或激活手动操作（开启），这对于启动计量泵非常有用。
多色 LED 指示灯
多色 LED 指示灯允许操作员快速检查控制器的状态。
绿色 = 仪表处于测量模式且读数低于设定点。
橙色/黄色 = 读数高于设定点且继电器处于活动状态。
闪烁红色 = 指示报警条件，例如超过最大给药时间。
保险丝保护计量触点
继电器计量触点的额定负载高达 2A，并受熔断器保护。
有标签的终端连接
快速连接端子块上有清晰的标签，便于连接电源、电导率探头和继电器，可用于操作计量泵、阀门、声音警报或灯。
